orange county recycles 30 million gallons of water a day, we recycle zero. we have a great opportunity to guarantee our water future and undo the damage to yosemite national park. >> sean, one point i know is the hydroelectric power generated by that dam, if i remember it's 41 million dollars? do i have my numbers right? >> there are a number of reasons why hetch hetchy is such a benefit to the city, not the least of which is that it produces carbon free public power to the city of san francisco. one of my favorite lines mike just used is this measure is about consolidating from 8 reservoirs to 7. another way to say that is to say this is about draining one of them, the hetch hetchy valley. have other studies said this is feasible? sure,
just like tearing down city hall or knocking down the golden gate bridge, that's possible but not feasible. we're not going to spend 3 billion dollars to tear down the hetch hetchy dam. let's not forget, we are also stewards for two dozen cities in the peninsula. over 2 million californians benefit from the foresight of our forefathers almost 100 years ago in building hetch hetchy. while the rest of the state is tying themselves up in knots trying to figure out where to get their water. not only did we have the type of water storage hetch hetchy provides, not only today but in the future, we are in a solid place. and to spend this kind of money, and let's just talk about the $8 million dollars, i think that's one thing we can agree on. this calls for us to spend $8 million dollars. in
my own district, out at like merced, we're taking that amount of money and building a water recycling plant. mike wants us to take that money and waste it on a report. why would we want to spend money to redo what's already been done? >> i upd. that does bring up an interesting point as well with the infrastructure that was voted on and is almost complete. can you address that investment that's already been made. >> absolutely. >> and also with the state of california's report suggesting that 8 million wouldn't be enough to get a plan done. so if you could just address those two points that have come up. >> sure, let me start -- again, go to the report it says again 7 million is what's needed for san francisco to engage in the planning process. the larger amount is if we
bring in the park service and the state of california, which at this point we don't need to do, we just need the san francisco public utilities commission to get off their butts and start to think about the future more effectively. this really boils down it a 21st century versus the 20th century view of water. sean says our future is secure. it isn't. anyone who thinks our future water supply is going to be coming from the tuolome river is crazy. the one thing we know about climate change is we have to change our water sources. again, we don't recycle any water. we're going to start importing water from daly city next week. we have some plans on the books to do 4 million gals by 2035. that's a fraction. the san francisco business times recbltly said san francisco's plans for the
future are baby steps and it's disgraceful. prop f is about getting us away from that vision and getting us to plan for the future. >> sean, as a wrap up, the dollars that we're talking about here, whether it's a values debate, that's one thing, that's some of the language that i respect. but when i look at the dollars, i'm not sure, could you dra*e address how that the city and the controller's report? it seems to be a fairly vast effect. >> there's no question, this is a significant impact on the city but let's translate that for our viewers. it's an impact on the rate payers. this is not born by the city's budget, it's borne by everybody's monthly water bill. we know everybody's water bill is going to climb because we have to rebuild our sewer system. on top of that do we want to add many hundreds or
perhaps thousands of dollars to conduct a rate study that has been done several times that is going to completely drain the stoerplg capacity we have and absolutely put the city further back tomorrow than where we are today? >> we're talking about lettinging the rate payers decide for themselves. it gives the rate payers the information they need in 2016 if it gets back on the ballot. the controller's report is actually quite inaccurate. it projects if prop f passes, a plan is implemented, adopted by the voters and hetch hetchy valley is restored that it will cost $10 billion dollars. that's not what people are voting on here. they are voting on prop f which is simply an $8 million dollar planning process. it's not just an $8 million planning process, it's voting for san
francisco's future and i urge people to go to restoreyosemite.org and read about it. >> this is a measure hoisted on san francisco by outsiders. every san francisco political group across the political spectrum opposes this measure. this will cost us billions of dollars and it's an unnecessary complete waste of our rate payer dollars. we've done the studies, we know it's a waste, let's move forward with what we're already doing which are significant recycled water projects across the city. >> thank you, gentlemen. we hope this discussion was informative. for more discussion on this and other ballot measures in this year's election, please visit the san francisco league of women voters web site at sfvotes.org.
remember, early voting is available at city hall from 8:00 am to 5:00 pm if you because we have a great waste water system here in san francisco, we do about 80 million gallons of waste water here in san francisco, which means we basically fill up 120 olympic sized swimming pools each and every day here in the city. we protect public health and safety and environment because we are discharging into the bay and into the ocean. this is essentially the first treatment here at our waste water treatment facility. what we do is slow down the
water so that things either settle to the bottom or float to the top. you see we have a nice selection of things floating around there, things from bubble gum wrappers, toilet paper, whatever you dump down the toilet, whatever gets into our storm drains, that's what gets into our waste water treatment and we have to clean. >> see these chains here, this keeps scum from building up. >> on this end in the liquid end basically we're just trying to produce a good water product that doesn't negatively impact the receiving water so that we have recreation and no bad impact on fish and aquatic life. solids is what's happening. . >> by sludge, what exactly do you mean? is that the actual technical term? . >> it's a technical term and
it's used in a lot of different ways, but this is organic sewage sludge. basically what it is is, oh, maybe things that come out of your garbage disposal, things that are fecal in nature. it's sludge left in the water after the primary treatment, then we blend those two over and send them over to digestion. this building is built to replace tanks here that were so odoriferous they would curl your hair. we built this as an interim process. >> is there a coagulant introduced somewhere in the middle of this? . >> this coagulant brings solids together and lets the water run through. that gives us more time in the
digestion process, more time to reduce the amount of solids. these are the biggest ones in the world, like we always like to do in san francisco. they are 4 meter, there's none like it in the world. >> really? wow. >> three meters, usually. we got the biggest, if not the best. so here we are. look at that baby hum. river of sludge. >> one of the things is we use bacteria that's common in our own guts to create this reduction. it's like an extra digestion. one of the things we have to do to facilitate that is heat that sludge up and keep it at the temperature our body likes, 98.6 degrees. >> so what we have here is the heat exchanger for digester no. 6. these clog up with debris and we're coming in to -- next wet weather season so we always
come through here, clean them out, make sure that we get maximum heat exchange during the colder wet weather. sludge season. >> rubber glove. >> right here. >> rubber glove, excellent. all right, guys. >> thank you. >> good luck. >> this is the full on hazmat. . >> residual liquid. we're taking it time to let it drain. we don't want to get sludge on it necessarily. take your time. stand on the side of it. . >> should we let it release for a while? . >> let it release. >> is that the technical term? . >> this is the most important bolt on the whole thing.
this is the locking bolt. it locks this thing right in place. so now. >> take your hammer and what we want to do, we get rag build up right in here. the hot water recirculates right in here, the sludge recirculates in here. the sludge sometimes has rags in it. all we want to do is go around the clean the rags. let me show you how. take the slide hammer, go all the way through the back, go around. >> got you. >> during the real rainy season, how does that change the way dealing with this job? is it a lot more stuff in there? . >> what we do, charles, we do this quarterly. every four months we go around and clean all the heat exchangers so we don't have a
large build up. . >> go around? . >> yeah. (sound of hammering). >> what i'm trying to do, charles, is always pull it out on the low stroke. >> right. so you are not, like, flying out. now talk about clean up. . >> then where does this stuff get deposited? . >> we're going to dump it in a debris box and it will go back to the plant. >> if you think back, the
romans came up with a system of plumbing that allowed us it use water to transport waste away from the hub of civilization, which enabled cities to grow. . >> you have a large bowl, a drive motor and another motor with a planetary gearbox with differential pressure inside there. the large mass up there spinning separating the solids from the liquid. we have to prevent about once a month, we go in there grease those, change the oil, check the vibration levels. the operators can tell just by the hum of that machine that it's a harmonic noise emitted that it's out of balance and the machine needs to be cleaned. it will start vibrating and we
have vibration analysis machines that will come over here and check the levels. so it's kind of an on-going thing that you have to stay on top of on a daily basis. >> handled properly, you take organic residuals, as we call them, that are leftovers of our society and turn them back into some energy. and we have another ability to take that sludge and get a nutrient value for crops there. we actually are running a kind of composting energy recovery system. >> well, this is a dirty job. we try to do it safely and we try to do it without imposing too much on the public. people want to flush their toilets and have things go away and not be bothersome again. we do a lot to try to accomplish that. i'd like to invite you to come back any time you want. once you got this in your
blood, you are not going to be able to stay away. the raging waters are fun and when we do digester cleaning i really hope you can come back. that's quite a sight. >> yeah, that sounds interesting. >> i really appreciate you coming by and it was a i'm derek, i'm hyungry, and ready to eat. these vendors offer a variety of the streets near you. these mobile restaurants are serving up original, creative and unusual combinations. you can grab something simple like a grilled cheese sandwich or something unique like curry.
we areher here in the average eight -- upper haight. you will be competing in the quick buy food challenge. an appetizer and if you are the winner you will get the title of the quitck bite "chompion." i am here with matt cohen, from off the grid. >> we assembled trucks and put them into a really unique heurban settings. >> what inspired you to start
off the grid? >> i was helping people lodge mobile food trucks. the work asking for what can we get -- part together? we started our first location and then from there we expanded locations. >> why do think food trucks have grown? >> i have gotten popular because the high cost of starting a brick and mortar or strong, the rise of social media, trucks can be easily located, and food trucks to offer a unique outdoor experience that is not easily replaced by any of their setting any worlwhere else in san franc. san francisco eaters are interested in cuisine. there adventuress. the fact theyuse grea use great
ingredients and make gourmet food makes unpopular. >> i have been dying to have these. >> i have had that roach coach experience. it is great they're making food they can trust. >> have you decided? >> we are in the thick of the competition? >> my game was thrown off because they pulled out of my first appetizer choice. >> how we going to crush clear? >> it will be easy. probably everyone has tried, something bacon tell us delicious. >> -- people tell us is
delicious. >> hopefully you think the same thing. >> hopefully i am going to win. we're in the financial district. there is a food truck right there. every day changes. it is easy and fun to go down. these are going to be really good. >> how are you going to dominate? >> i think he does not know what he is doing. >> i was thinking of doing [unintelligible] we are underrepresented. >> i was singing of starting an irish pub. that was my idea. >> one our biggest is the corned beef and cabbage. we are asking people what they're thinking in getting some
feedback. >> for a lot of people i am sure this combination looks very wrong. it might not sound right on paper but when you taste it to or have it in your mouth, it is a variety. this is one of the best ways in creating community. people gather around and talk about it and get to know different cultures. that brings people together and i hope more off the grid style and people can mingle and interact and remove all our differences and work on our similarities. this creates opportunity. >> the time has come and i am very hungry. what have you got? >> i got this from on the go, a sandwich, and a caramel cupcake. i went with home cooking.
what de think? >> i will have another bite. >> sounds good. >> that was fantastic. let's start with you. >> i had the fried mac and cheese, and twinkies. i wanted to get something kind of classic with a twist on it. >> it was crispy. >> i will admit. >> want to try fieried mac and cheese? >> was that the best twinkie? >> would you say you had the
know, they're doing it fast. so, i want to know. >> not knowing how to navigate the internet is at a loss of what to do. >> we don't have a computer. >> we are non-profit that unites organizations and volunteers to transform lives through digital literacy. our big right now is the broadband technology opportunity program, a federally funded project through the department of aging so we're working in 26 locations, our volunteers are trained to be tutors and trainers offering everything from basic classes all the way to genealogy and job search. >> to me, a computer aon auxiliary brain, it's like knowing how to use your brain, how important is that. i think it's important and
possibly seniors, it's important for them to stay in touch. er >> people like facebook or skype so they can connect to their family members or see their family member's albums from far away. >> (speaking spanish). >> what we like to focus on is transferring skills from volunteer to learner to help them get on to facebook, find housing on craig's list, being able to connect with friends and family. >> i decided teaching them what i knew and that got me into wanting to give back and to learning more and how it works. >> i discover -- i discovered
that seniors need a lot of review. >> i am beginner so little by little, i learn a lot now. >> i learned just the basics, if you get the basics, you can learn it, if you don't get the basics, you're lost. >> it's simple, it's easy, once you know it and that's what i want to learn, how to make my life easier and more knowledgeable with a computer. >> so, what we need right now are more people who speak languages other than english or in addition to english, who can give their time during the day and who care deeply ideally about helping to close the digital divide. >> you know, its's a humbling experience, it could be something simple to us in our daily lives but to someone that doesn't know and to help somebody gain that experience in any way, it's awesome. >> (speaking spanish).
>> no matter how tired or cranky or whatever i miekt feel when i walk into this class, i walk out feeling great. >> if you feel comfortable using a cuter and you have patience, we want you on our team. >> with they showed me how to do skype. >> will you help me learn more? >> it is my pleasure to introduce our moderator this evening, professor almondover. he joined the uc davis school of law in 2004,
